If a vCPU is in running state while this ioctl is invoked, the vCPU may
experience inconsistent filtering behavior on MSR accesses.
Note, invoking this ioctl with a vCPU is running is inherently racy. However,
KVM does guarantee that vCPUs will see either the previous filter or the new
filter, e.g. MSRs with identical settings in both the old and new filter will
have deterministic behavior.
